摘要： A handheld, hand-guided cutting-off machine (10), which includes a rotating cutting-off wheel, a supporting housing part (36), an output shaft, which is rotatably supported around an output axis (40), a drive motor, a transmission mechanism (19), which connects the drive motor to the output shaft, a flange and a safety guard (24), which covers the cutting-off wheel over a covering area. The cutting-off wheel is rotatably fixedly mounted on the output shaft with the aid of the flange and surrounded by the safety guard (24), which is pivotable around a pivot axis. The safety guard (24), the supporting housing part (36) and the transmission mechanism (19) have maximum distances from the output axis (40) over an outcut angle (θ), which are less than or equal to half the flange diameter of the flange.

摘要： A handheld power tool has a switchable gear component actuatable by a selector switch. The gear component moves from a first operating position into a second operating position. The selector switch has a first switching position associated with the first operating position and a second switching position associated with the second operating position, and movable so that intermediate positions are assumed. A traveling coupling between the selector switch and the gear component has a spring exerting force onto the gear component in the first direction. A locking bolt is coupled to the selector switch in a positively driven manner. In the intermediate positions, the locking bolt is moved into a blocking bolt position blocking movement of the gear component out of the first operating position into the second operating position. When the selector switch is in the second switching position, the locking bolt is in a releasing bolt position.

摘要： A hand-guided tool apparatus having a braking device for braking a machining tool is disclosed. The tool includes a rear handle for operating the tool apparatus, a drive device for driving the machining tool about an axis of rotation, a belt brake including a brake drum and a brake belt which is wrapped around the brake drum, and an operating device including a gas switch for activation of the drive device and a safety switch for unlocking the gas switch. The gas switch and the safety switch are disposed on the rear handle. The operating device additionally includes a brake switch, which is separate from the gas switch and from the safety switch, for activating the belt brake, and which is disposed on the rear handle and is connected to the brake belt by a transmission device.
